Product Description:


The tyre trolley transfers the concrete segment to the rear of the launching gantry. The lifting trolley of the gantry lifts the concrete segment to the assembly position and the steeve hangs up the segment. After assembly, these segments tighten together with stressing wires, and the gantry put the beam on the pier and fulfill the construction of bridge segment. Based on the requirement of our client and the bridge conditions, the erection span and lifting capacity could be modified and customied for each machine.

Q:Weight of 120 ton bridging machine
0.65m/min (40 m and 120 tons beam) - 0.75m/min (30 m and 100 tons beam) 0.95m/min (30 m, 80 tons beam), the vertical speed of the crane: 6.6m/min 7, crane cross.
Q:Now the high-speed rail bridge frame span of the beam
Bridge crane is a crane, because its main function is to lift the beam, and then transported to the location and put down
Q:The difference between the bridge erecting machine and machine
Simple said bridge building machine is in bridge abutment on-site pouring concrete formwork, and the bridge erecting machine is dipping prefabricated in bridge abutment.
Q:How many tonnage bridge erecting machine needs to install the monitoring system
RJ-104 type hoisting machinery information management system can realize the real-time management of the site, a number of projects on the regional multi class operation bridging machine information and safety state, to facilitate the realization of regional information management needs of remote bridging machine.
Q:How to weld the wet joint of bridge erecting machine
Specifically how much I do not know, but the specification can be found
Q:Bridge crane is a bridge crane should be classified as
Bridge crane is a bridge crane should be classified as that? Is it called bridging machine 5Chj201010 | browse 464Recommended 2016-06-25 22:18:20 best answerThe bridge erecting machine is a device for placing a prefabricated beam on a prefabricated pier. Bridge crane is a crane, because its main function is to lift the beam, and then transported to the location and put down. But it is very different from the general sense of the crane. The requirements of the harsh conditions, and the existence of the beam on the line, or called the longitudinal shift. Bridge machine is divided into the erection of highway bridges, conventional railway bridge, passenger dedicated railway bridge, etc..
Q:How much is a bridging machine
The preliminary estimate can be calculated according to the weight of steel structure. Unit price of about 1.5~2 yuan / ton.
Q:What is bridging agent? What is the main purpose?
This product is a white cylindrical crystal, insoluble in water, soluble in ethanol, ethyl ether, benzene, isopropyl benzene and other organic solvents…
Q:Detection and quality standard of bridge erecting machine
The bridge erecting machine is a device for placing a prefabricated beam on a prefabricated pier. Bridge crane is a crane, because its main function is to lift the beam, and then transported to the location and put down. But it is very different from the general sense of the crane. The requirements of the harsh conditions, and the existence of the beam on the line, or called the longitudinal shift. Bridge machine is divided into the erection of highway bridges, conventional railway bridge, passenger dedicated railway bridge, etc..
Q:What should be done before the erection of the bridge girder
The bridge erecting machine is a device for placing a prefabricated beam on a prefabricated pier. Bridge crane is a crane, because its main function is to lift the beam, and then transported to the location and put down
